I was looking at several recent threads related to the 3B+ issue, and they all seem to peter out without a new boot image. The images on the FTP server do not show updates, so am I right in assuming that the 3B+ is not a feasible platform?

Is there a single issue that is causing this problem, or could it be fixed by booting on a Pi2/3 and then doing a update/upgrade?

There appears to be an issue with Kolibri provided by worldpossible but it is possible to install Kolibri directly.
I have tried to put together some notes from what I had to do to get things to work. You are welcome to have them they are at giakonda.org.uk/technical

Thanks for linking. There should be no reason to install Kolibri separately on the pi. The Kolibri image includes Kolibri and ReadMe_Kolibri.pdf includes instructions on how to install Kolibri channels the Kolibri way.

Hi James
I an in Zambia at the moment out of contact most of the time. There is one issue I think you may be able to fix that would help a lot. If you could add the DHCP address to the RACHEL startup banner it would help enormously.
Sorry if this seems rude.
Kind Regards
Howard

This was a bug in the showip function in common.php from the content shell due to the command output changing since the last time a RACHEL image was made and the last time the content shell was updated for the pi. This will be fixed in future images. If you want to fix it on an existing system you can edit the common.php file at /var/www/admin/common.php by removing “addr:” from the preg_match lines in showip. Lines 754 and 756 in this file on github but it will be a bit different on your device as other changes were made.
